Magos Biologis not found in the three locations


I played the story mission "Chapter Two , Saving Caius Thorn, Search for the Magos Biologis" in coop and the magos was not found at any location. Now I have no new story missions (I still should search the magos biologis at the three locations) but  that is not possible.

Please fix this!
